This is course book for both the Comptometer and the Burroughs calculator. It consists of 40 lessons, with an emphasis on addition, but also covers subtraction, multiplication and division. Its pages have perforations, so that when the answers to an exercise are filled in, it can be torn out and handed in to the teacher. This may make this book somewhat rare to find despite having been very widely used as an alternative to Felt & Tarrant's Comptometer Course for Business Training. There were five editions - 1940, 1947, 1952 (shown here), 1959, and 1964.
